MILKING-MAGHINE.

Specification of Letters Patent.

Application filed. September 21, 1911.. ScrialNo. 650,985;

To all whom it may concern.-

Be' it known that 1, JOHN HUGGLER, a citizen of the United States, and a resident oflndianapolismounty of Marion, and State of Indiana, have invented a certain useful lllilking-lviachine; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings.

The object of this invention is to provide a machine for milking cows and other animals which shall be of simple construction with but few parts and easily operated such that the operation of milking may be speedily performed and the stripping process be done efiiciently without any injury to the animal.

A further object is to provide a machine which shall- 'be. easily cleansed but which:

portions which surround the teats of the animal and with power driven means for drawing downthe milk, theaction of which closely resembles the milking action of the human hand. I

A further feature .lies in the means for adjusting the positions of the teat holders to fit diiierent animals.

The nature ofthe invention will be understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a partialsection midway of the device, Sl'lQWlIW. alli of the fingers in operative position. Fig. 2 is a horizontal section on the line 22 of Fig. 1. Fig. 3 is a section entire line 33 of Fig. 1. Pi 4. is a vertical section on the line 4-4 0" Fig. 3, with portions removed and showing the operating cone.

Indetail there is shown in the drawings a milking machine applicable to a cows udder I 40 with a cover'lO, base 11, and teat holders walls of said teat holders actuated by the 12 mounted upon adjustable arms 13 which are supported upon said base 11 and having operating fingers 14 extendingthrough the 1 rotationof the cone 15 which has bearing in said cover 10 and base 11.

The teat holders 12 are formed after the fashion; of a partially closed hand and consist of two parts, a stationary part 16 having a downward projection 17 through a slot 18 in the adjustable arm 13 and secured in position by a nut 19 on said projection 17 and a movable portion 20 secured by spring hinge 21 to the stationary portion 16. A spring latch 22 secures the two parts when i tially midway thereof through which extend four milking fingers 14. Said milking fingers are reciprocably mounted in and are held in alinement by the stationary part 16 of the teat holder and an upward extension 23 from the innen end of said stationary part 16. The ends of the fingers 14, which are pushed within the teat holder, have rounded cushioned heads and by means of. springs 24 surrounding the fingers 14 and pressing against the bearing23 and collars 25 secured on' the fingers, the rounded inner ends of said milking.- fingers- 14 are forced against the operating cone 15', hereafter described.

The adjustable arms 13 have looped inner ends 26 which surround an annular projec- .tion 27 from the lower-side-of the base 11. One of said arms is in alinement with its loop, see Fig. 1, but the other three loops are offset slightly in order that they may have bearing on the said annular pro ection to hold the loop portions of the arms-13 together and their outer ends in alineinent.

Thecone 15 is mounted upon a' shaft 28 which has bearin s in the cover 10 and. in

a plug 29 which 15 threaded within the ennular projection. 27, .see Fig. 1. vSaid cone 15 has two oppositely disposed recesses 31 in the surface thereof extending spirally about the cone from leftto right, asseen in Fig. 4. The rate of taper of theconeis substantialdiy the sameas that of the animaPs teambtit the taper of the cone extends in the opposite direction. from that-in the teat holder, that is, it flares outwardly from the top. The fingers 14 are causedto bear against the cone 15 by the springs 24andloit-g' meeting the recessed portions 3]. will be withdrawn from the teat holder. The lower end of the shaft 28 is shouldered down and said shouldered portion 33, preferabl y square in cross section, fits within a corresponding socket on the end of a flexible shaft 35 which is driven from any desired source of power.

To operate the machine the hinged portions 20 of the teat holders 12 are thrown open, as shown by the dotted-lines on the lower part of Fig. 3, and the whole device lifted so that the cover 10-will press upwardly against the central underside of the udder of the animal to be milkedand the teats will lie against the stationary portions 16 of the teat holders after which the teat holders 20 are closed about the teat and power is applied to the flexible shaft 35' and the cone 15 caused to revolve. As the cone revolves, the recesses therein will come opposite the fingers 14 whereupon they will be pressed inwardly by the springs 21. Furtherrotation of the cone will force the fingers 14 outward and cause them to press,

in turn, against the teats within the teat holders. The recesses 31 on the face of the cone 15 are so designed and so positioned on the cone that the upper finger, as shown in Fig. 1, will be the first to be pressed outwardly, being followed by the second, third and fourth fingers, in turn. Thus it will be seen that the passage in the teat will be closed by the first or upper finger and as the lower fingers are forced outwardly by the cone, they, in turn, will have the same action in forcing the milk downwardly as do a mans fingers in milking. The last or fourth finger serves to press the last of the milk out of the teatand causes a thorough stripping action. A further purpose of having recesses lying spirally about the cone is that the lower or fourth finger will remain in its outward position until. the three upper fingers have been released, thus allowing the milk to flow downwardly into the teat, and until the first or upper finger is forced outwardly. Thus it will be understood that there is always a gripping of the teat and it would be possible to use this machine without supplying any means for supporting it from the ground. The cone here shown has two recesses, but more could be used without departing from the spirit of the invention. As often happens the distance between teats varies on different animals and to provide for this, the teat holder 12 can be adjusted along the arm 13 by means of the slot 18 and nut 19, as before described, moving them either toward or away from the cone. The length of the fin--.

gers 14 remains the same, but the plug 29 may be unscrewed from the annular projection 2'1, thus withdrawing the cone 15 and another cone, larger or smaller asthe case may demand, may replace it after which it is inserted within the casing and the plug 29 screwed into the base. The arms 13 may be moved about the projection 27 to provide the necessary lateral adjustment should two of the teats be closer together than the other two, see dotted lines in Fig. 3.

A very material advantage of this device over'any of the so-called suction milking machines lies in the fact that the animal cannot be injured by the working of the machine after all of the milk has been withdrawn from the udder, for it has been found by experience, first by hand milking and later by machine milking, that this hand motion-or its imitation will not in any way injure the teat, neither bruising it nor dilating the opening nor can blood be thus drawn from the teat.

I claim as my invention:
